摘　　要：城壕油田西259区于2008年6月全面投入开发,主要开采层位长3,区块储层物性差、油井见水后含水上升快、单井产能低及隔夹层发育引起吸水剖面不均等因素影响,制约了油藏稳定高效开发,针对以上问题,本文探讨和研究区块治理对策,开展注采调控、流压调整、剖面挖潜、细分层注水、油水井双向堵水等相应稳产技术探讨和研究,提出区块下步稳产方向,从而为油田开发技术政策调整奠定了基础。X259 block of Chenghao oilfield developed overall in Aug. 2008. The production oil layer is Chang-3. In this area, many factors are need to be considered, such as poor for- mation properties, water flooding quickly in oil production wells after water-cut increase, lower oil production rate, and inconsistent water injection profile with interlayer existed in the formation. All of the factors restrict the efficient oilfield development. Consider about the technical problems above, we will discuss the oil production measures in this paper, which contain the injection and production rate adjustment, bottom hole pressure controlling, well profile study, subdivision layer of well injection, water plugging between production well and water injection well. Based on the discussions, we will propose the technical methods of reservoir stability for further adjustments.
